A generator is a device that converts mechanical energy into electrical energy. This conversion is based on the principle of electromagnetic induction, where a relative motion between a conductor and a magnetic field induces an electric current in the conductor. Mechanical work is done to cause this relative motion. A motor is a device that converts electrical energy into mechanical energy. A voltmeter is an instrument used to measure electric potential difference (voltage). An ammeter is an instrument used to measure electric current.
The electrical device used for converting mechanical energy into electrical energy is called
